Bad moods can actually be good for you, with an Australian study finding that being sad makes people less gullible (輕信), improves their ability to judge others and also boosts memory.
The study, authored by psychology professor Joseph Forgas at the University of New South Wales, showed that people in a negative mood were more critical of, and paid more attention to, their surroundings than happier people, who were more likely to believe anything they were told.
"Although positive mood seems to promote creativity, flexibility, cooperation, and reliance on mental shortcuts, negative moods trigger (引發(fā)) more attentive, careful thinking, paying greater attention to the external world," Forgas wrote.
"Our research suggests that sadness ... promotes information processing strategies best suited to dealing with more demanding situations."
For the study, Forgas and his team conducted several experiments that started with inducing happy or sad moods in their subjects through watching films and recalling positive or negative events.
In one of the experiments, happy and sad participants were asked to judge the truth of urban myths and rumors and found that people in a negative mood were less likely to believe these statements.
People in a bad mood were also less likely to make snap decisions based on racial or religious prejudices, and they were less likely to make mistakes when asked to recall an event that they witnessed.
The study also found that sad people were better at stating their case through written arguments, which Forgas said showed that a "mildly negative mood may actually promote a more concrete, accommodative and ultimately more successful communication style."
"Positive mood is not universally desirable: people in negative mood are less prone to judgmental errors, are more resistant to eyewitness distortions（扭曲）and are better at producing high-quality, effective persuasive messages," Forgas wrote.
The study was published in the November/December edition of the Australian Science journal.

A growing number of health, hunger, and sustainable （可持續(xù)的）agriculture groups today announced plans for Food Day-a nationwide campaign to change the way Americans eat and think about food．Food Day will encourage people around the country to sponsor or participate in activities that encourage Americans to “eat real” and support healthy, affordable food grown in a sustainable, humane way．
Organizers hope Food Day will inspire Americans to hold thousands of events in schools, college campuses, houses of worship and even in private homes aimed at fixing America’s food system．A Food Day event could be as small as a parent organizing a vegetable identification contest at a kindergarten class-or as massive as a rally（集會）in a city park, with entertainment and healthy food．Health departments, city councils and other policy makers could use Food Day to launch campaigns, hold hearings, or otherwise address communities food problems．
The campaign will advocate progress toward five central goals:
·Reducing diet-related disease by promoting healthy foods．The American diet is too low in fruits, vegetables, and whole grains and too high in fatty meat, soft drinks and salty packaged and restaurant foods-contributing to hundreds of thousands of premature deaths each year．
·Supporting sustainable farms and stopping subsidies to agribusiness．Billions of federal dollars a year would be better spent helping environmentally conscious family farmers than hugeagribusiness operations．
·Expanding access to food and alleviating hunger．Far too many Americans don’t know where their next meal is coming from, or have access to fresh produce in their neighborhood．
·Reforming factory farms to protect animals and the environment．Farming of animals can and should be done without cruelty, and without degrading the quality of life．
·Curbing junk-food marketing to kids．Food companies should not be targeting children with foods that promote tooth decay, obesity and other health problems．
小題1:What is the best title of the text?
A．Food Day CampaignB．Eat Real and Keep fit
C．How to Observe Food DayD．Food Problems in the USA
小題2:What can we learn from Paragraph 2?
A．Food problems are not easy to deal with．

D．People are invited to create their own Food Day events．
小題3:One of the aims of Food Day is to ____．
A．target children with junk foodB．operate more agribusiness
C．increase access to foodD．cancel a series of events
小題4:The underlined word "curbing" in the last paragraph is closest in meaning to “          ”．
A．controllingB．enlargingC．evaluatingD．providing
小題5:We can infer from the text that _____．

    Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu may make a difference in how long the misery lasts.
The American Lung Association (ALA) has issued new guidelines on combating colds and the flu(流感), and one of the keys is being able to quickly tell the two apart. That’s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.
The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses - flu A, B and C. There is no cure for either illness , but the flu can be prevented by the flu vaccine, which is, for most people, the best way to fight the flu, according to the ALA. But if the flu does strike, quick action can help. Although the flu and common cold have many similarities , there are some obvious signs to look for.
Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.
The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms.
Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome(綜合癥) ，a rare but serious condition of the liver and central nervous system.
There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.
　
小題1: According to the author, knowing the cause of the misery will help ________.
A．shorten the duration of the illness
B．the patient buy medicine over the counter
C．the patient obtain cheaper prescription drugs
D．prevent people from catching colds and the flu
小題2: We learn from the passage that ___________.
A．one doesn’t need to take any medicine if he has a cold or the flu
B．a(chǎn)spirin should not be included in over-the-counter medicines for the flu
C．delayed treatment of the flu will harm the liver and central nervous system
D．over-the-counter drugs can be taken to ease the misery caused by a cold or the flu
小題3: According to the passage, to combat the flu effectively, ___________.
A．one should identify the virus which causes it
B．one should consult a doctor as soon as possible
C．one should take medicine upon catching the disease
D．one should remain alert when the disease is spreading
小題4:Which of the following symptoms will distinguish the flu from a cold?
A．A stuffy nose. 　　B．A high temperature.
C．A sore throat.　　D．A dry cough.
小題5: If children have flu-like symptoms, their parents _______________.
A．a(chǎn)re advised not to give them aspirin
B．should watch out for signs of Reye syndrome
C．a(chǎn)re encouraged to take them to hospital for vaccination
D．should prevent them from mixing with people running a fever

Feel tired lately? Has a doctor said he can’t find anything wrong with you? Perhaps he has sent you to a hospital, but all the advanced equipment there shows that there is nothing wrong with you.
Then, consider this: you might be in a state of sub-health（亞健康）. Sub-health, also called the third state or gray state, is explained as a borderline（界限）state between health and disease.
According to the survey by the National Health Organization, over 45 percent of sub-healthy people are middle-aged or elderly. The percentage is even higher among people who work in management positions as well as students around exam-week.
Symptoms include a lack of energy, depression, slow reactions, insomnia, anger, and poor memory. Other symptoms include shortness of breath, sweating and aching in the waist and legs.
The key to preventing and recovering from sub-health, according to some medical experts, is to form good living habits, alternate work and rest, exercise regularly, and take part in open air activities.
As for meals, people are advised to eat less salt and sugar. They should also eat more fresh vegetables, fruits, fish because they are rich in nutritional elements -- vitamins and other elements that are important to the body.
Nutrition experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract（消化道）. They also say that a balanced diet is very helpful in avoiding sub-health.
小題1:.
According to this passage, which of the following is true?
A．When you are in a state of sub-health, you should stay at home and keep silent.
B．When you are in a state of sub-health, you should go to see a doctor and buy some medicine.
C．When you are in a state of sub-health, you should have yourself examined in foreign countries.
D．When you are in a state of sub-health, you should find out the reasons and relax yourself.
小題2:.
. It may be easy for middle-aged people to get sub-healthy because _________.
A．they have used up their energyB．they have lost their living hopes
C．they have more pressure in life and workD．they begin to get older
小題3:.
. The key to preventing you from falling into a state of sub-health is that you should ________.
A．work hard B．sleep more
C．form good living habits D．take more medicine
小題4:.
. The underlined word “alternate” in this passage is closest in meaning to _________.

Too cold for recess?  School policies vary as much as temps
When is it too cold for schoolchildren to go outside for recess（課間休息）? The answer varies widely based on where a school is located and what the kids are used to.
Consider:  One northern Minnesota school says it has to be 15 below zero before kids are kept inside. But in areas along the East Coast, temperatures below 35 to 40 degrees could keep kids inside. Canceling recess because of the cold is no small issue considering that much of the USA is trembling through what may be its coldest winter in a generation, according to AccuWeather.
There is no national temperature standard for when to keep kids inside during the winter months, the U.S. Department of Education says. Decisions are made at the local level, either by principals or school districts.
Consequently, policies are all over the map:
? In International Falls, Minn., the self-described "Icebox of the Nation," where the average high temperature in January is 13 degrees, Falls Elementary School Principal Jerry Hilfer says, "if it's 15 below (or warmer), they go out, no matter what." "At 20 below, it gets iffy," he adds.
? In Wicomico County, Md., principals typically keep children indoors when temperatures drop below freezing, or if it's raining or snowing, says Susan Jones, the school system's director of elementary education.
"That's the bottom line," says Curtis Twilley, principal of Pemberton Elementary School in Salisbury, Md. Twilley says students get little exercise when recess stays indoors. At Pemberton Elementary, the students will typically play board games or computer games in a classroom because the school's gym is occupied with other classes, he says.
? For schools in Marquette, Mich., which averages about 12 feet of snow per season, school officials acknowledge students are probably a little more prepared than those in some more mild climates.
小題1:Which of the following is not true according to the passage_________.
A．No national temperature standard is made for when to keep kids inside during the winter months.
B．Susan Jones insists students get little exercise when recess stays indoors.
C．In Wicomico County, children are kept indoors when temperatures dip below freezing.
D．Mich has about 12 feet of snow per season on average.
小題2: Which place calls itself Box of Ice?
Wicomico County  B. Marquette    C.Salisbury       D. Minn
小題3: Considering_______, canceling recess In USA because of the cold is a big issue.
A．different schools have different principles.
B．much of the USA has very cold winter.
C．physical activity can boost student performance.
D．decisions are made at the local level,
小題4: The underlined word iffy means _______.
A．uncertain B．surprisingC． seriousD．worse
小題5: What will be talked about next?
A．More school policies
B．The reasons why school policies vary.
C．Measures to improve the situation.
D．Necessities to improve the situation

To get an extra 14 years of life, don't smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount．That is according to a study published this Monday in the Public Library of Science Medicine Journal．
After tracking more than 20,000 people aged 45 to 79 years in the United Kingdom from about 1993 to 2007, Kay-Tee Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived all average of 14 years longer than those who didn't．
“We've known for a long time that these behaviors are good things to do, but we've not seen this benefit before, ”said Susan Jebb, head of Nutrition and Health at Britain's Medical Research Council．“The benefit was also seen regardless of whether or not people were fat and what social class they came from．”
Study participants（參與者）scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake．
Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes．But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years．
“We can't say that any person could gain 14 years by doing these things, ”said Dr．Tim Armstrong, a physical activity expert at the World Health Organization．“The 14 years is an average across the population of what's theoretically（理論上地）possible．”
“Most people know that things like a good diet matter and that smoking isn't good for them, ”Susan Jebb said．“We need to work on providing people with much more practical support to help them change．”
小題1:Which of the following DOESN'T belong to the four healthy habits?
A．Eat five servings of fruits and vegetables a day．
B．Do proper exercise in the morning every day．
C．Drinking alcohol in the proper amount every day．
D．Having a cigarette before going to bed every day．
小題2:We can learn from the passage that            ．
A．Susan Jebb did not take part in the study．
B．the study observed people as well as tested specific changes．
C．there's no need for people under 45 to adopt these good habits．
D．only those from first class can benefit from these healthy behaviors．
小題3:What can be inferred from the passage?
A．All the people are well aware of the harm of their bad habits．
B．People aged 45 to 70 have bad habits in the United Kingdom．
C．Governments should take measures to help people change their bad habits．
D．People have adopted the four healthy habits after knowing they're good．
小題4:What would be the best title for this passage?
A．Smoking and Drinking Cuts You 14 Years
B．How to Live a Much Healthier Life
C．Healthy Habits May Give Extra 14 Years
D．How to Make Your Life Longer Than Others

Smoking, which may be a pleasure for some people, is a series of discomfort for their fellows. Medical scientists have expressed their concern about effect of smoking on the health not only of those who smoke but also those who do not smoke. In fact, non-smokers who take in the air polluted by tobacco smoke suffer more than the smokers themselves. A great number of students are trying to persuade the university to forbid smoking in classrooms. Believe they are completely right in their aim. However, I think it more important to achieve this by calling on the smokers to use good judgment and to show concern for others. Smoking is not allowed in theaters, cinemas and in other public places. Therefore, smoking must be forbidden in our classroom. Although many people have passed away for having smoked a lot and we call on people to give up smoking, yet many more that are following will turn down what we say every day, above all, the young people smoke a lot more.

Football is so popular in China. Almost everyone is interested in the sport — young and old, boys and girls, and now even robots.
Last week at Hangzhou Guangming Middle School, kids from several schools played football with their robots.
Robot football was very different from human football. Only two robots played in each match. The field was as big as a ping-pong table. One half was black and the other was white. Each robot tried to catch the “football” and score a goal. The robot with more goals won.
Gao Linge, a boy from Guangming Middle School, helped make one of the robots for the match.
“My school bought the main board (主板),” said Gao, 14. “Then I decided what my robot looked like and made a computer programme for it.”
Gao’s robot was eight centimeters tall and had two arms. It had four sensors (傳感器) to “see” and “kick” the football.
Ying Xuehai, a 12-year-old student from Gao’s school, also made a robot. His robot played against Gao’s. The match decided who would go to the final game. Ying lost the game. So he gave many of his robot’s parts to Gao.
Even so, Gao’s robot didn’t win the final. It played well in the first five minutes. Then it slowed down. By the end of the match, it could hardly move. What was wrong? Gao and Ying found the problem — their robot ran out of batteries (電池)!
“We’ll solve the problem and beat the other school next time!” said the two boys.
小題1: How many robots are needed in one match?
A．Only one.B．Two.C．Three.D．Four.
小題2: The third paragraph mainly talks about ________.
A．a(chǎn) wonderful robot football game.B．how to let robots score more goals
C．the rules of the robot football games.D．the way for robots to win the match
小題3: Why did Gao Linge lose the final?
A．Because his robot had no power.B．Because he broke the rules of the match.
C．Because he used Ying Xuehai’s parts.D．Because his robot went wrong.
小題4: From the passage we know that if you want to take part in the match, ________.
A．you must go to Hangzhou.B．you must know something about computers
C．you must know how to play football on the playground
D．you must get along with Gao Linge and Ying Xuehai

A super drug that could remove Alzheimer’s (老年癡呆癥)，heart disease and diabetes (糖尿病) and help people live to 100 is being developed by scientists. Their research is based on the identification of three genes that help prolong lives and prevent diseases which occur in old age. Medically controlling the proteins made by the “ longevity genes” will allow millions to live longer, predicts Dr Nir Barzilai.
Those whose DNA strongly features the three genes are 80 percent less likely to develop Alzheimer’s. The genes also fight against the deadly impact of smoking, poor diet, obesity and lack of exercise.
Already, several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage old age. “ The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing,” he said.
Of the three longevity genes, two genes increase the production of so-called good cholesterol(膽固醇), which reduces the risk of heart disease. The third prevents diabetes. They were discovered by Dr Barzilai’s team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the group, which shared relatively few common ancestors, was 20 times more likely to hit the entury. Dr Barzilai said: “ 30 percent of them were obese or overweight and 30 percent smoked two acks of cigarettes a day for more than 40 years, however they can live to 100.”
But Andrew Ketteringham of the Alzheimer’s Society said: “Alzheimer’s disease, a most common disease, is likely to be caused by a combination of genetic disosition(遺傳傾向), lifestyles and life events. Many genes are probably involved.
小題1:Some people are able to live to 100 years because of ______.
A．a(chǎn) magical medicineB．three special genesC．good living habitsD．longevity proteins
小題2:Why does the discovery of the longevity genes mean a lot?
A．Because it can bring great benefits to scientific labs.
B．Because it can help people change their unhealthy genes
C．Because it helps produce a drug that can make people live longer.
D．Because it will help scientists build up a new branch of biology.
小題3: From Paragraph 4 we can infer that ________.
A．longevity genes can create good cholesterol.
B．the volunteers share some common ancestors
C．bad habits are likely to have no effect on the volunteers
D．longevity genes protect the volunteers against bad habits
小題4:What is Andrew Ketteringham’s attitude toward the study?
A．PositiveB．NegativeC．CriticalD．Cautious
